ro ALL WHoM 1T 'MAY oNoERN:

Be itjkno'wn thot`I, W. S. MAAC-KINTQSIYI, oi' Pittsburg, in the county of Allegheny, and State of Pennsyl- I venin, have invented a new and useful 'Improvement in Rollers for Forming and Finishing Car, Wagon, and other Axles; Vandl do hereby declare that, the following is a'full, clear, andex'act description thereof, which will enable those skilled ,in4 the art to make and use the same, reference being had to thc'aecompanying drawings, forming part of this specification. Y i' I l This invention relates toal new and improved method of constructing rollorsfor formingand finishing the axles of cars or Wagons, whereby the same are more economically and perfectly formed and finished.

It consists of apnir of rollers, rotating in suitable boxes in a frame, connected togetherrand to the power by spur-gear wheels, the faces of the said rollers being cut'into grooves of such form as will cause the heated iron, when forced into said grooves, to assume the desired form.

Said grooves may be of any desired number, each one, being smaller and nearer to the desired form than the one next before it.

The drawing is a front view ofmy invention.

A is a. bed-plate.

B is the roller-frame.

C are set-screws.

a aregroovesrin the` rollers D.

D are the rollers.

E are the spur-gear wheels.

al is the shaft of the ripper `roller.

F isa. crank. I I

a2 are indentations or enlargements, wider than the grooves a., and beingI part of ther same, by means ofY which shoulders or irregular lines and surfaces areffo'rmed on thefaxle.V

Upon any bed-plate A is erected u. frame, B', provided with suitable boxes in the sides thereofpt receive the bearings of the rollers D, in the ordinary'way, as shown, said frame being proyi'ded with suitable set-screws, C, by means-of which the rollers D are set together, also inthe ordinary way. y I

Said rollers are placed one over the other, having their axes phrallel to each other, ned are connected together by the spurgeared wheels E, keyed to the-axles of thesame, in the lordinary wey, snid'rollers D being driven by any power 4applied Vto the shaft' o, as by a. crank, Ili', as shown in the drawing.

The/rollers D are metallic rollers,'and may be of any convenient length, and must have n'circumference otl least as great as the length of the nxleto be formed. v

Said rollers D have cuter cost into the faces or surfaces of the same the grooves a, so as the grooves a in thc under roller D shall exactly correspond with'the grooves@ in the upper roller D, as shown. i

The grooves a :1re either cut or least' entirely around the rollers D, as shown in the middle groove inthe drawing, or4 said grooves a may extend so A,for around the some as to be equal to the length of the axle to be formed, and are made so as to receive theheated metal between the rollers.D,.and in the grooves'a of the saine, and form the same into the' exact shape of the spacesbetween the under and upperiparts of. the said grooves a, the grooves a being widened or enlarged by the indentations or enlargements a2, so as to form shoulders or irregular lines and surfaces on the axle to loe-formed, the grcovesfa and the enlargements a2 always being of a. form so ns that the under and upper parts of the same will form the axle or other article to be made in the desired shape, the centre groove a, or the groove all around the rollers D, being of a semioireular form in `each'roller, the object of the same being to work the iron to any'required size before the same can be worked into axles.

Each of the grooves a may be deeper and larger than the one next to the same Von one side, so as that` the axle may be formed in` one groove ond more perfectly formed in another groove a, und smoothed and finished in another of saidrgrooves.' i

'and other vehicles, the advantages oi" which nre that the lThe operntion is readily seen from the above description and the drawing.

l Constructed as above described, itl constitutes n convenient apparatus for forming the-axles of cars, wagons, `sanne are thereby 'more perfectly and economically formed.' v

I olaimes new, sn'd desire to secure by Letters PotenterEhe rollers D, having grooves thereon, eonstrncted `and an' for the purposes set forth.
